Ball mills are the most commonly used piece of equipment for milling. However, vibratory mills, attrition mills, and fluid energy mills also are used. Crushing and grinding typically are dry processes; milling may be a wet or dry process. In wet milling, water or alcohol commonly is used as the milling liquid.

In ball mills, the comminution or grinding effect greatly decreases inwardly from the outer wall on account of the damping which occurs to the movable bodies by means of the grinding material. Therefore, with larger grinding containers, the comminution output becomes unsatisfactory and with increased volume, the grinding effect diminishes.
